Correct Answer is A

Explanation

A. Troponin T: Troponin T remains elevated for 10 to 14 days after a myocardial infarction. This protein is highly specific for cardiac muscle injury and is used to confirm myocardial infarction.

B. Creatinine phosphokinase: Creatinine phosphokinase (CPK) typically returns to normal levels within 3 days after a myocardial infarction, so it would no longer be elevated at this point.

C. Myoglobin: Myoglobin rises early after a myocardial infarction but is not specific to heart muscle and returns to normal within 24 hours, so it would not be elevated at this time.

D. Creatinine kinase-MB: Creatinine kinase-MB (CK-MB) usually returns to normal levels within 2 to 3 days after a myocardial infarction, so it is unlikely to still be elevated 6 days later.

A. "Was your son born with this cardiac defect?" B. "Has your son had a sore throat recently?" C. "Has your child had any injuries recently?" D. "Are you aware that your son will have to be in isolation?"

Correct Answer is B

Explanation

A. "Was your son born with this cardiac defect?" Rheumatic fever is an acquired condition, often following a streptococcal throat infection, not a congenital (born with) cardiac defect.

B. "Has your son had a sore throat recently?" Rheumatic fever commonly follows a streptococcal throat infection, so asking about a recent sore throat is relevant and important for diagnosis.

C. "Has your child had any injuries recently?" Recent injuries are unrelated to the development of rheumatic fever and are not a pertinent question.

D. "Are you aware that your son will have to be in isolation?" Isolation is not typically required for rheumatic fever, as it is not contagious in this stage.
